Climate scientists talking about dragons and monsters?!!

Why? Because they're scared and terribly worried about our future as capitalist-driven global warming races past the old 1.5°C do-not-cross line.
__________________________________

“The goal to avoid exceeding 1.5C is deader than a doornail. It’s almost impossible to avoid at this point because we’ve just waited too long to act,” said Zeke Hausfather, a research scientist at Berkeley Earth. “We are speeding past the 1.5C line in an accelerating way, and that will continue until global emissions stop climbing.”

The 1.5C target now appears to be simply a rhetorical rather than scientifically achievable one. “I never thought 1.5C was a conceivable goal. I thought it was a pointless thing,” said Gavin Schmidt, a climate scientist at NASA.

“I’m totally unsurprised, like almost all climate scientists, that we are shooting past it at a rapid clip," Schmidt said. "But what matters is we have to reduce emissions. Once we stop warming the planet, the better it will be for the people and ecosystems that live here.”

As the world barrels past 1.5C there lie alarming uncertainties in the form of runaway climate “tipping points,” which once set off cannot be halted on human timescales, such as the Amazon turning into a savanna, the collapse of the great polar ice sheets, and huge pulses of carbon released from melting permafrost.

“1.5C is not a cliff edge, but the further we warm up, the closer we get to unwittingly setting off tipping points that will bring dramatic climate consequences,” said Grahame Madge, a climate spokesman at the UK Met Office.

“We are edging ever closer to tipping points in the climate system that we won’t be able to come back from; it’s uncertain when they will arrive, they are almost like monsters in the darkness,” Madge said.

Hausfather added, “Every tenth of a degree matters. All we know is that the more we push the climate system away from where it has been for the last few million years, there be dragons.”

This is truly scary.

It might be another example of Mother Nature saying: FAFO, you fools.

An international team of scientists using observations from satellites found evidence that Earth's total amount of freshwater dropped abruptly starting in May 2014 and has remained low ever since. The researchers say the shift could indicate Earth's continents have entered a persistently drier phase.

From 2015 through 2023, satellite measurements showed that the average amount of freshwater stored on land — that includes liquid surface water like lakes and rivers, plus water in aquifers underground — was 290 cubic miles (1,200 cubic km) lower than the average levels from 2002 through 2014. According to Matthew Rodell, one of the study's authors, "That's two and a half times the volume of Lake Erie lost."

It remains to be seen whether global freshwater will rebound to pre-2015 values, hold steady, or resume its decline. Considering that the nine warmest years in the modern temperature record coincided with the abrupt freshwater decline, Rodell said, "We don't think this is a coincidence, and it could be a harbinger of what's to come."

And that titanic amount of extra heat is doing serious damage to Earth's climate and environment.

In August and September, huge portions of South America were shrouded in intense smoke from wildfires raging in the Amazon and other parts of Brazil and Bolivia. The Brazilian Pantanal — the world’s largest tropical wetland — had an almost eightfold increase in wildfires this year compared to 2023. From Manaus to São Paulo and Buenos Aires, the smoke, visible from space, blurred sunlight for weeks and posed a threat to the health of millions.

The occurrence raised alarms, but some experts warn that in the future, it might not be such an extraordinary episode.

South America is becoming drier, warmer, and more flammable, according to a new study. These conditions favor not only natural wildfires but also the uncontrolled spread of human-caused fire.

Greetings all, this is my #introduction

I came to #science writing as a reporter first, explaining fracking as rigs went up in neighborhoods 20 years ago. Later, our town was the first Texas city to ban the practice.

Recently, I collaborated with a brilliant researcher and clinician writing a book that makes the science of human behavior accessible to caregivers--so their loved ones with autism can be happy and make progress.

I'm all in, y'all. Writing science in plain language is vital.


Scientific American Loses Its Bold Leader

Denialism isn't a political stance, it's a philosophical one. That's why both right- and left-wing people indulge in it.

Anybody who can be convinced that something is true against evidence otherwise is wide open to being convinced regarding denialism — of anything. HIV/AIDS, COVID, transgender, sexism, racism, etc.

Which is why political efforts to defeat denialism will never work. The only way to defeat it is through education, from kindergarten up. All age groups, all the time.

I think I am one of the only people of my generation (or maybe the last generation) who heard the word "meme" in the scientific context first.

I heard it in uni maybe in 2nd or 3rd year when one of my friends gave a talk about simulating evolution using software. Then, just one or two years later I started seeing the word "meme" pop up on the English-speaking internet literally everywhere.

For 15 out of the last 16 months — beginning in July 2023 and continuing through October 2024 — the average global temperature has been more than 1.5°C above the pre-industrial average.

That’s what Business As Usual is doing to us.

BASIC Co-Inventor Thomas E. Kurtz has Passed Away.

It’s with sadness that we note the passing of Thomas Eugene Kurtz, on November 12th. He was co-inventor of the BASIC programming language back in the 1960s. The legacy of his work lives on in the generation of technologists.

The origins of BASIC lie in the Dartmouth Timesharing System, like similar timesharing operating systems of the day, designed to allow the resources of a single computer to be shared across many terminals. In this case the computer was at Dartmouth College, and BASIC was designed to be a language with which software could be written by average students who perhaps didn’t have a computing background. In the decade that followed it proved ideal for the new microcomputers, and few were the home computers of the era which didn’t boot into some form of BASIC interpreter. Kurtz continued his work as a distinguished academic and educator until his retirement in 1993, but throughout he remained as the guiding hand of the language.

“Thomas Eugene Kurtz (Feb. 22 1928–Nov. 12, 2024) was an American mathematician, computer scientist and co-inventor, with John Kemeny, of the BASIC programming language and Dartmouth Timesharing System.”


The data is clear. Those, who are experts and actually scientifically investigate these topics have no doubts. Why do we not act? Why are people in huge numbers voting for politicians, who ignore what is known and are not only sacrificing our and our childrens' future, but already our presence?

Astronomers have just discovered the first known "Einstein zigzag."

Due to a rare, lucky cosmic alignment, the combined gravity of two galaxies bent light like spaghetti & split a distant quasar into six different images.

This six-part image could allow a very accurate measure of the expansion of the universe.

Visualization of the optical paths of the lensed images. The two zig-zag paths, D and F, are marked in pink and blue respectively. The deflectors cause two sets of sharp turns, while the smooth curvature seen in all paths is due to the expansion of space.

Trees and land absorbed almost no carbon dioxide (CO2) last year, and scientists are struggling to work out why.

Carbon sinks, such as forests, oceans and soils, are an essential part of regulating the Earth’s climate. Through natural processes, these land and ocean masses absorb almost half of all human carbon emissions from the atmosphere.

But preliminary findings for 2023 – the hottest year ever recorded on Earth – have found that the amount of carbon absorbed by forests, plants, and soil has temporarily collapsed.

This was completely unexpected, and therefore not something factored into most predictions and calculations about how quickly the Earth will heat up as a result of climate change. The breakdown of the land carbon sink could be temporary, but if it isn’t, this will drastically increase the rate of global heating.

It will be impossible for the world to reach net zero without carbon sinks, because there is simply no human technology that can absorb carbon on the same scale as the forests, grasslands, peat bogs, and oceans of the world.

There is no sign of the transition away from burning fossil fuels that was pledged by the world’s nations a year ago, with 2024 on track to set another new record for global carbon emissions.

The new data comes from the Global Carbon Budget project, a collaboration of more than 100 experts led by Prof Pierre Friedlingstein, at the University of Exeter, UK, who said: “The impacts of climate change are becoming increasingly dramatic, yet we still see no sign that burning of fossil fuels has peaked. Time is running out and world leaders meeting at Cop29 must bring about rapid and deep cuts to fossil fuel emissions.”

I wish they'd just be honest and announce that they have absolutely no intention of meeting any of their goals. Ever.

Last week, we had a story about scientists who put bats on a treadmill. This week, a neuroscientist teaches rats to drive. And they love it!

From @ConversationUS: "We crafted our first rodent car from a plastic cereal container. After trial and error, my colleagues and I found that rats could learn to drive forward by grasping a small wire that acted like a gas pedal."

The Copernicus Climate Change Service, a European Union organization that monitors global heating, announced on Thursday that the year 2024 will be 1.5 degrees Celsius warmer than pre-industrial levels. That means humanity has passed a critical threshold established in 2015 in the Paris climate accord.

“After 10 months of 2024, it is now virtually certain that 2024 will be the warmest year on record and the first year of more than 1.5ºC above pre-industrial levels," Samantha Burgess, deputy director of the Copernicus Climate Change Service, said in a statement. "This marks a new milestone in global temperature records and should serve as a catalyst to raise ambition for the upcoming Climate Change Conference, COP29.”

The EU agency announced this moment as nations all over the world gather in the Azerbaijani city of Baku for the 29th Conference of the Parties. The ERA5 dataset found that global temperatures in 2024 were on average 1.55 degrees Celsius higher than the 1.48 degrees threshold measured in 2023. The report also noted climate change-fueled major weather events in 2024 such as torrential floods in Spain and rapidly melting Antarctic sea ice.

From @LiveScience: Emerging evidence suggests that plate tectonics may have begun much earlier than previously thought — and may be a big reason that our planet harbors life. Some scientists are now arguing that plate tectonics emerged very soon after Earth's formation — perhaps predating life itself. Read more: https://flip.it/9nLsjW

So, you'll recall in the late-1930s the UK & other countries (including the US) benefitted from a large scale exodus of scientists & other intellectuals... indeed, there's been a lot of recent work done on how these migrants informed & shaped British cultural institutions across the 30s/40s/50s & beyond.

Are we now going to see a similar exodus of US scientists & others, who will then have a similar galvanising effect on their new/host countries scientific & cultural lives?

I somehow had never heard of cloud chambers before. With the help of condensing vapors at cool temperatures, you can see the actual paths of particles with your own eyes.

Not only can you see electrons, and protons, but you also see the interactions between particles. And cloud chambers have been used in physics since the 1920s, wild!

Not that any of us really want to read MORE bad news this week. But — this is the world we live in.

Turning away from it and closing our eyes does not change things. I believe it's important to know just where we stand and what we face so we can make the best choices in how we should live.

Also, note that this essay was published before this week's disastrous US election, which means that you can expect conditions warned about here to get even worse, sooner rather than later.
_______________________________________

In recent years, environmental warnings have become impossible to ignore. Humanity has pushed Earth far beyond its natural limits, launching it into a cascade of intertwined disasters that scientists now call the “polycrisis.” No longer a distant threat, this crisis is unfolding before us, destabilizing the foundations of ecosystems, economies, and communities worldwide.

While some hold out hope for a turnaround, the brutal truth is that we are too far gone. The trajectory is set, the damage done, and there is no miracle solution on the horizon. Our only option is to live through this polycrisis as best we can, facing an uncertain and increasingly harsh reality.

As temperatures climb, ecosystems crumble, and resource conflicts rise, it’s clear that our world will never be the same. For those of us with young families, our hopes are tempered by a haunting reality: the future we once dreamed of has shifted beyond reach. What remains is an obligation to understand the forces shaping this collapse, accept the inevitability of hardship, and try to adapt as the familiar falls away.
_______________________________________

The essay includes sections on climate change, biodiversity loss, economic and social erosion, and finally, "living through the polycrisis." I hope you'll find it helpful.
